ABBASID, TEMP. AL-MA’MUN (194-218h) Dinar, without mint-name, 210h Obverse: Reform type with double marginal legends Reverse: letter mim below, double circle inside marginal legend Weight: 3.47g References: cf Bernardi 116 (without mim); cf Lowick 454 (without mim). Edge shaved, otherwise almost extremely fine and very rare. The legends on this coin are almost identical to al-Ma’mun’s mintless reform coinage, issued in Iraq between 206-210h. However, the presence of an extra letter on the reverse appears to be otherwise unknown for this series, and the calligraphy suggests that it may in fact be an issue from the Yemen. If so, the letter mim may refer to Muhammad b. Ziyad, amir of Yemen.

Estimate: GBP 1200 - 1500
